ELECTRICIANS OR PLUMBERS TORCH.

SPECIFICATION forming part of Letters Patent No. 626,723, dated June 13, 1899.

Application filed- April 17, 1899. Serial No. 713,301. (No model.)

To all whmn it may concern:

Be it known that I, HIRAM O. ROBERTS, a citizen of the United States, residing in the city and county of Philadelphia, in the State of Pennsylvania, have invented certain, new and useful Improvements in Electricians or Plumbers Torches, of which the followingis a specification.

My invention relates to the class of plumbers torches which are each provided with a metallic air nozzle ad 3' ustably mounted thereon in such position that the discharge mouth of such nozzle is located in the vicinity of the torch wick, with the result that air discharged from said mouth directs the flame against any particularpart of a pipe orfixture upon which an operator may be at work.

Inasmuch as the distance of the flame from the top of the wick tube is apt to vary from time to time under diiierent conditions of the wick and burning fluid, it is a desideratum that the nozzle should be capable of very quick and easy vertical adjustment, to carry the discharge mouth of said nozzle to the successive points at which, under varying conditions of the flame, the air can be most advantageously driven against it.

My invention aims to provide a plumbers torch with an air pipe nozzle of a simple, novel, and inexpensive construction, and so mounted and applied that while capable of being very quickly and easily shifted from one position to another with respect to the flame, it is nevertheless automatically retained very securely in any position in which it may be set until manually carried to a new position of adjustment.

In the accompanying drawings I show, and herein I describe, a good form of a convenient embodiment of my invention, the particular subject matter claimed as novel being hereinafter definitely specified.

In the accompanying drawings,

Figure 1 is a vertical central sectional elevational view of a torch vembodying a good form of my invention.

Figure 2 is a top plan view of the same.

Figure 3 is a view in perspective of the spring removed from its mounting in the structure.

Figure 4 is a view in perspective of the upper portion of the nozzle.

Similar letters of reference indicate corre sponding parts. I

In the accompanying drawings,

A is the body of the structure, provided with a wick tube B, equipped with a disk 0, which constitutes the cap or lid of said body, and which when seated upon the upper end of said body, supports the wick tube and centers it with respect to said body.

The cap 0 is, as shown, preferably arranged in threaded engagement with the upper portion of said body. v

D is an annular projection formed upon or carried by the protruding upper end of the wick tube, and, being milled as to its periphery, constitutes a very convenient head, so to speak, through which rotation may be imparted to the cap 0 for screwing and unscrew ing the latter from its-seat.

The lower portion of the wick tube is pref erably provided with a series of wall openings 1), of any preferred character.

E is a cap of usual construction secured by a flexible connection e to any convenient portion of the structure.

In the drawings I show said flexible connection as provided with a ring 6 which encircles the neck of the wick tube below the projection or head D.

The cap, as is well understood, may be seated upon the upper end of the wick tube to extinguish the flame and to prevent the evaporation of the burning fluid when the device is not in operation.

The air pipe nozzle G, the lower end of which is encircled by the end of an air pipe 4 I, in communication with a source of air supply or pressure,is formed as a short metallic tube of any preferred,although preferably quadrangular,section, and secured as to its body within two keepers g g conveniently formed of plates of metal, each secured as to both ends to the body of the structure, and each as to its intermediate portion passing snugly about the nozzle.

H is a bow spring formed of flat plate metal, disposed between the nozzle and the body of the structure, and, being as shown, upwardly arched, its respective end portions bear against said body and'its intermediate portion bears against said nozzle.

Said spring is disposed between the keepers g g and abuts as to its respective shoulders h against the opposing edges of said keepers, and, being of length slightly in excess of the distance from the inner face of one keeper to the inner face of the other, it is permanently maintained by said keepers in its slightly bowed or curved condition.

Prolongations of tongues h at the ends of said spring extend through the keepers and secure the spring against displacement.

The upper end of the nozzle is curved inwardly so that its end extends'into the vicinity of the upper end of the wick tube, and the area of the discharge outlet being much smaller than the transverse area of the nozzle the air blast discharged from said mouth is concentrated and veryeffective to throw the flame in any desired direction.

Manifestly pressure of the thumb against the outer surface of the nozzle between the keepers will compress the spring H, and movement of the thumb, while still depressing the 'spring, in an upward or downward direction,

will carry said nozzle up or down as the case may be. Manifestly, furthermore, as soon as the thumb is removed from the 'nozzle, the spring will at once automatically bind it in its new position.

This adjustment of the nozzle may be made instantaneously so to speak, and without. any formal unscrewing or unlocking it from one position and screwing or looking it in a new position.

Having thus described my invention, I claim-- 1. An electricians and plumbers torch consisting of a body provided with a wick tube, keepers mounted on said body, an air nozzle, the upper end of which is inturned and adapted to discharge a blast in the vicinity of the upper end of the wick tube, which nozzle is movably mounted in said keepers, and a sisting of a body provided with a wick tube,

keepers mounted on said body, an air nozzle the upper end of which is inturned or adapted to discharge a blast in the vicinity of the upper end of the wick tube, which nozzle is movably mounted in said keepers, a spring mounted between said body and nozzle and "engaged against the keepers and arranged to bear against said air nozzle, a cap mounted on said wick tube and adapted to the upper end of the body, and an annular projection mounted on the upper end of the wick tube, substantially as set forth.

3. An electricians and plumbers torch consisting of a body having a threaded upper end and provided with a wick tube, keepers mounted on said body, an air nozzle of quadrangular plan, the upper end of which is ini turned or adapted to discharge a blast in the vicinity of the upper end of the wick tube, and has a mouth of transverse area less than that of the body of the nozzle, which nozzle is movably mounted in said keepers, a spring mounted between said body and nozzle and engaged against the keepers and arranged to bear against said air nozzle, a threaded cap mounted on said wick tube and adapted to the threaded upper end of the body, and an annular projection mounted on the upper end of the wick tube, substantially as set forth.

In testimony that I claim the foregoing as my invention I have hereunto signed my name this 6th day of April, A. D. 1899.

HIRAM O. ROBERTS.
